Materials that have higher fluorescence emission in the solid state than molecules in solution have recently been paid more attention by the scientific community due to their potential applications in various fields. In this work, we newly synthesized ben

The increased number of N-atoms induced a blueshift in absorption and a gain in fluorescence quantum yield, from 750 nm and ～0% for pyrrole to 635 nm and ～40% for triazole, respectively. DFT calculations indicated a decrease in HOMO energy levels with the
Synthesis of optically active polyheterocycles containing pyrrolidine, imidazole, and 1,2,3-triazole rings

Optically active polyheterocycles containing pyrrolidine, imidazole, and 1,2,3-triazole units were obtained via a multistep synthesis with the [3+2] cycloaddition of Boc-protected (S)-(pyrrolidin-2-yl)methyl azide with 2-ethynylimidazoles in the presence of CuI (CuAAC reaction) as the key step. Typical for terminal alkynes, the reactions occurred regioselectively and 1,4-disubstituted 1,2,3-triazoles were formed exclusively. The deprotection of the pyrrolidine N-atom was performed by treatment with TFA under standard conditions.
