Organic Compounds03:02

Organic Compounds

All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and synthetic compounds that contain carbon. Although a single, precise definition has yet to be identified by the chemistry community, most agree that a defining trait of organic molecules is the presence of carbon as the principal element, bonded to hydrogen and other carbon atoms. However, some carbon-containing compounds such as carbonates, cyanides, and...
What is Organic Chemistry?02:17

What is Organic Chemistry?

Organic chemistry is the study of compounds of carbon called organic compounds. Organic compounds either originate from living organisms or are synthesized by chemists. A defining trait of these compounds is the presence of carbon as the principal element, which is bonded to other carbon atoms and other elements such as hydrogen, oxygen, nitrogen, and sulfur. The existence of a wide array of organic molecules is a consequence of carbon atoms’ ability to form up to four strong bonds to other...
Characteristics and Nomenclature of Homopolymers01:00

Characteristics and Nomenclature of Homopolymers

Polymers that are made up of identical monomer units are called homopolymers. Only one repeating unit is involved in the construction of the homopolymer structure. For example, as depicted in Figure 1, polypropylene is a homopolymer constituted of propylene monomers. Here, the only repeating unit in the polymer chain is propylene.
Pore Transport and Ion-Pair Transport01:17

Pore Transport and Ion-Pair Transport

Pore transport and ion-pair formation are critical mechanisms for the absorption and distribution of drugs in the body.
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited  but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct microscopic...
Chemistry of the Cell02:58

Chemistry of the Cell

The cell is chemically composed of water, organic molecules and inorganic ions.
Water
The polarity of the water molecule and its resulting hydrogen bonding makes water a unique substance with special properties that are intimately tied to the processes of life. Life originally evolved in an aqueous environment, and most of an organism’s cellular chemistry and metabolism occur inside the aqueous contents of the cell’s cytoplasm. Special properties of water are its high heat capacity and heat of...
Structure of Porins01:21

Structure of Porins

Mitochondria, chloroplasts, and gram-negative bacteria have transmembrane, beta-barrel proteins called porins to mediate the free diffusion of ions and metabolites across the membrane. Mitochondrial porin precursors contain conserved amino acid sequences called beta signals at their C-terminal. Beta signals have a  motif of PoXGXXHyXHy (Po-Polar, X-Any amino acid, G-Glycine, Hy-LargeHydrophobic), which are crucial for precursor recognition to initiate precursor assembly. Beta-barrel precursors...

Area of Science:

  • Materials Science
  • Supramolecular Chemistry
  • Organic Chemistry

Background:

  • Most synthetic porous materials utilize extended networks (1D, 2D, or 3D), such as metal-organic frameworks.
  • Discrete molecules typically pack densely in the solid state, resulting in non-porous materials.
  • Recent research explores porous materials constructed from discrete organic molecules.

Purpose of the Study:

  • To review recent advancements in discrete organic molecules exhibiting solid-state porosity.
  • To categorize these porous organic molecules as intrinsically porous (covalent cavities) or extrinsically porous (packing voids).
  • To highlight the potential benefits of organic porous materials over inorganic or hybrid systems.

Main Methods:

  • Review of existing literature on porous discrete organic molecules.
  • Categorization based on porosity origin (intrinsic vs. extrinsic).
  • Analysis of advantages including solubility, component diversity, and structural dynamics.

Main Results:

  • Discrete organic molecules can form porous crystalline or amorphous solids.
  • Intrinsic porosity arises from permanent covalent cavities within molecules.
  • Extrinsic porosity results from inefficient molecular packing.
  • Organic porous materials offer advantages in solubility, tunability, and responsiveness.

Conclusions:

  • Discrete organic molecules represent a promising alternative to traditional porous frameworks.
  • Their unique properties, such as solubility and responsiveness, open new avenues for material design.
  • A vast, largely untapped potential exists within known cage-like organic molecules for creating novel porous systems.
