The present invention relates to a class of compounds of general formula (I) or their salts of general formula (II): In formula (I)-(II), the substituents (A)p and (SOH)n on the benzene ring are at the ortho, meta or para position, n is 0-2, and p is 0-3; M is selected from Li, Na, K, NHor organic ammonium salt NRRRR, where R, R, R, Rare the same or different H, Calkyl groups, cyclohexyl groups, CHCHOH, CH(CH)CHOH or benzyl groups; where p&#x3e;0, A stands for the same or different groups selected from: H, CN, NO, NH, F, Cl, Br, Calkyl group, cyclohexyl group, phenyl group, benzyl group, phenoxy group, Calkoxy group, Calkylthio group, SOCH&#x2550;CH, SOCHCHA, NRCORor NRSOR.

Anthrapyridone sulfonic acid compounds and their preparation methods and applications

The disclosure provides fluorescence probe compounds of formula I, their preparation methods and applications. These compounds are useful in detecting mercury ions.

Fluorescent probe compounds, preparation method and use thereof

The invention is related to a weather-resistant dye and use thereof, which contains in molecules thereof not only chromophoric parent D, but also electron-accepting group Q which is linked with dye parent D through non-conjugated carbon link L to constitute D-L-Q dye molecule; the electron-accepting group Q has such a HOMO energy level that is lower than the HOMO energy level of the dye chromophoric parent D. The dye has sun-resistance and anti-ozone performances, which can be used as colorant in the ink, dope, lacquer, toner powder for laser printing, marker, paper, fabric, glass, porcelain or polymer.

Weather-resistant dye and use thereof
