Abstract:Organic second-order nonlinear optical (NLO) chromophores are the main constituent part of nonlinear optical material. Scientists are dedicated to researching on the synthesis of novel chromophores with excellent performance by the facile design and modification of organic second-order NLO chromophores for decades. However, the researches on NLO chromophores in order to achieve the efficient translation of molecular microscopic nonlinearity (hyperpolarizability β) into macroscopic electro-optic (EO) coefficien… Show more
“…1–4 H 2 S can induce sensory discomfort, stimulate the nervous system, and in severe cases lead to poisoning or even rapid death. 5–7 Functioning as a signaling molecule, H 2 S plays a pivotal role in several crucial physiological processes including blood pressure regulation, nerve conduction, and oxidative stress inhibition. 8–10 Elevated levels of H 2 S have been associated with various conditions including Alzheimer's disease, Down syndrome, Parkinson's disease, and diabetes.…”
The fluorescent probe PPF-CDNB based on the asymmetric π-conjugated phosphine structure of phosphorfluorene can highly selectively and sensitively detect hydrogen sulfide in live cells, and exhibits a significant fluorescence enhancement effect.

We show the strategy of introducing a suitable conjugated site-isolator on the bridge of a nonlinear optical chromophore to significantly improve the electro-optic activity at the shortwave infrared window (850 nm) for electro-optic modulation.
