General description

Trimethoxy(2-phenylethyl)silane (TMPES) is a phenyl functionalized trialkoxy silane that can be used as a siloxane based precursor.

Application

TMPES can be used as a silane-based coating on quantum dot (QD) light emitting diodes to improve the adhesion of QDs and improve the thermal stability of the device. It may be used in the synthesis of pure silica zeolite molecular sieves.

The development of porphyrin-embedded mesoporous organosilicate materials for application to the detection of volatile hydrocarbon solvents is described. Design of the receptor and optical indicator construct begins with parallel selection of the porphyrin indicator and design of the mesoporous sorbent.

Principles of sol-gel chemistry were utilized to create silica- and germania-based dual-ligand surface-bonded sol-gel coatings providing enhanced performance in capillary microextraction (CME) through a combination of ligand superhydrophobicity and π-π interaction. These organic-inorganic hybrid coatings were prepared using sol-gel precursors
