High-efficiency generation of harmonics in polythiophene

, 2021
High-efficiency harmonic generation is observed in a semiconducting polymer RR-P3HT [regioregular poly(3-hexylthiophene)], which exhibits a high nonlinear susceptibility [χ (2) > 10−6 m V−1] under pumping by a pulsed fibre laser.

Fluorescence modulation of eosin Y in a PMMA film by diarylethene switching

Mendeleev communications (Print), 2019
A switchable fluorescence system has been prepared based on an eosin Y fluorophore and a photochromic diarylethene. The fluorescence emission was switched between the ‘on’ and ‘off’ states via photochromic isomerization.
