Abstract:
Two isomeric pyrenodithiophenediones and their triisopropylsilyl(TIPS)-ethynyl-functionalized derivatives were synthesized and characterized. With treatment of excess lithium TIPS-acetylide, the isomeric diones could undergo Michael and carbonyl additions to form three derivatives with four, three, and two TIPS-ethynyl groups, respectively. The isomeric TIPS-ethynyl-functionalized derivatives show different physicochemical properties. The single-crystalline transistors based on TIPS-ethynyl-functionalized derivatives exhibit a promising p-type transport behavior, with hole mobilities up to 0.51 cm2 V-1 s-1.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

Isomerism in Alkenes
An isomer is called cis-2-butene when the methyl groups are on the same side of the double bond, and the other stereoisomer, in which methyl groups are on the opposite side of the double bond, is called trans-2-butene. The cis and trans stereoisomers are not...
Relative Reactivity of Carboxylic Acid Derivatives
A key factor in assessing the reactivity of the acid derivatives is the basicity of the substituent or the leaving group. The lower the basicity of the leaving group, the higher the reactivity of the derivative. The basicity of the leaving group follows this order:
Halide ions < Acyloxy ions < Alkoxy ions < Amine ions
Transfer RNA Synthesis
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...
