Synthesis and optical properties of tetraphenylmethane-based tetrahedral fluorescent compounds and their water-soluble PEG-linked polymers

The synthesis and optical properties of tetrahedral fluorescent compounds comprising of tetraphenylmethane as the core and oligothiophenes as the chromophoric arms, and their water-soluble poly(ethylene glycol)-linked polymers are reported.

Tetraphenylmethane or silane-based compound as well as preparation method and application thereof

The invention provides a tetraphenylmethane or silane-based compound shown in formula (I), a preparation method of the tetraphenylmethane or silane-based compound and application of the tetraphenylmethane or silane-based compound in synthesizing an electrochromic material membrane as a monomer. As the tetraphenylmethane or silane-based compound has a space structure of tetrahedral tetrad, through membrane formation with electrochemcial polymerization, the obtained membrane expresses larger specific surface area and good electrochemical performance such as electrochromism and the like at the same time. The contrast of the membrane is 30-80 percent, the response time of the membrane is between 0.5s and 6s, the contrast and the response time both express reasonable electrochemcial stable activity, and experimental results show that the material is a potential electrochromic material. The formula of the tetraphenylmethane or silane-based compound is shown in the description.
