A novel pyridyltriphenylamine-rhodamine dye PTRh and a pyridyltriphenylamine derivative PTO were synthesized and characterized by 1H NMR and HRMS-MALDI-TOF. PTRh performed typical fluorescence resonance energy transfer (FRET) signal from pyridyltriphenylamine to rhodamine along with notable color change from green to rose when interacting with Hg2+ in EtOH/H2O. And PTRh as a ratiometric probe for...
Nonlinear optical multipolar chromophores with nitro acceptors were designed and synthesized. The target compounds were characterized by NMR, IR, UV and melting point. The decomposition temperature was determined with differential scanning calorimetry, and the absorption spectra were measured. The first hyperpolarizability of the chromophore were calculated via solvatochromic methods. The nonlinear...
