Area of Science:

  • Materials Science
  • Organic Electronics
  • Molecular Engineering

Background:

  • Electron-transport layers are crucial for organic electronic devices.
  • Developing solution-processable materials with controlled molecular orientation is challenging.
  • Phthalimide and triazine units are known for their electronic properties.

Purpose of the Study:

  • To design and synthesize a star-shaped molecule for use as an electron-transport material.
  • To achieve solution processability via a cleavable protecting group strategy.
  • To investigate the effect of processing on molecular orientation and film morphology.

Main Methods:

  • Synthesis of a star-shaped molecule with tert-butoxycarbonyl (Boc) protected precursor.
  • Solution processing and thermal annealing to remove Boc groups.
  • Optical absorption spectroscopy, 2D-grazing incidence X-ray diffraction (2D-GIXD), and p-polarized multiple-angle incidence resolution spectrometry (pMAIRS) to characterize the film.

Main Results:

  • The designed molecule, featuring phthalimide units on a triazine core, was successfully synthesized.
  • Annealing the Boc-protected precursor resulted in a transparent film with an absorption edge at 339 nm.
  • The molecular orientation transitioned from random to face-on during Boc group removal, yielding a low-crystallinity, oriented-amorphous structure.

Conclusions:

  • The developed molecule and its processing method enable the formation of an oriented-amorphous electron-transport layer.
  • This structure is advantageous for enhancing charge transport in organic electronic devices.
  • The findings offer a new pathway for fabricating high-performance organic light-emitting diodes (OLEDs) and solar cells.
