NOVELTY - Bisphenol S molecular imprinted mesoporous silica complex comprises silica matrix, substrate binding moieties, alkyl amine and quantum dot. The alkylamine contains amine-based compound (I). USE - The complex is useful in sensor, preferably fluorescence spectrometer or fluorescence reader for detecting bisphenol S (all claimed). ADVANTAGE - The complex can effectively detect bisphenol S with high sensitivity and selectivity. DETAILED DESCRIPTION - Bisphenol S molecular imprinted mesoporous silica complex comprises silica matrix, substrate binding moieties, alkyl amine and quantum dot. The alkylamine contains amine-based compound of formula (asterisk-CjH2j-NH2) (I).j = 1-5, where asterisk is connection site with the silica matrix. INDEPENDENT CLAIMS are also included for: (1) precursor of bisphenol S derivative of formula (II); (2) producing bisphenol S molecular imprinted mesoporous silica complex comprising (a) reacting the precursor of the bisphenol S derivative (IIa) with the silica precursor of formula (SiA'3Bm) (III), (c) performing sol-gel reaction by adding tetraalkoxysilane, (d) forming a void (cavity) by acid treatment, and (e) encapsulating the quantum dots; and (3) sensor comprising the bisphenol S molecular imprinted mesoporous silica complex. G1 = CjH2k'-1; P' = CjH2j; k' = 1-5; A' = halo or alkoxy group of formula (OCxH2x+1); x = 0-4; Bm = alkyl-based compounds of formulae (-(CH2)n-AN) (Ia), (-(CH2)n-CA) (Ib), or (-(CH2)n-ZW) (Ic); n = 1-6; AN = anion or acid, preferably -COO-, -SO3- , COOH and/or SO3H; CA = cation, base, and/or cationic heterocyclic group comprising N, preferably -NR2, -NR3+, and/or imidazole groups; and ZW = zwitter ion; and R = H or 1-4C alkyl.
