Photoresponsive polymers with dangling triptycene units as efficient receptor for fullerene‐C₆₀

Abstract

We report herein a new triptycene derivative (1) with an azo functional group.This molecule has been used as a monomer to yield two linear polymers (TAFPs) that have several triptycene units dangling from the linear polymer chain. TAFPs are soluble in organic solvents and are thermally stable. TAFPs can be cast into thin films. Further, these polymers are fluorescent with emission intensity increasing upon irradiation with ultraviolet light due to photoisomerization of the azo groups present in them. The fluorescence of TAFPs are quenched in the presence of C 60 , which supports their strong affinity for each other. Since both TAFP1 and TAFP2 form stable thin films of uniform thickness over large area coupled with their interaction with C 60 , these polymers may find potential applications in the development of optoelectronic devices or as molecular sensors in supramolecular chemistry.

Thermally Stable and High-Surface-Area Triptycene and Phenanthroline-Based Microporous Polymer for Selective CO2 Capture over CH4 and N2

“…The existence of 3D-triptycene in the backbone of polymers or materials with its internal free volume (IFV) confers intrinsic microporosity and its rigid robust structure yields high thermal stability . Utilizing these special features of triptycene, researchers have been able to design triptycene-based materials in recent years for use in sensing, electronics, liquid crystal displays, gas capture and separation, , host–guest chemistry, and molecular machines . In this research work, we have described the synthesis, characterization, and adsorption characteristics of a porous polymer (TPPM) utilizing triptycene and 2,9-dichloro-1,10-phenanthroline as monomers.…”
