摘要：

Photoresponsive arylsilanes have been fascinating molecules for decades because of their unique photophysical characteristics and surface chemistry. Here we report the synthesis and fabrication of a crystalline two-dimensional trisilyl metal-organic framework (TSiMOF) orderly installed with the classical photoresponsive hexamethyltrisilane groups on the surface. Irradiated by UV light under air in minutes the fluorescence of the TSiMOF is turned on simultaneously with an intriguing surface transformation from superhydrophobic to hydrophilic. Thus, multifarious luminescent and hydrophilic patterns including logos, characters and Quick Response codes, etc. with good resolution are readily generated on the facilely fabricated TSiMOF film. The mechanism of this transformation is revealed by control experiments that the superficial trimethylsilyl groups suffering photochemical oxidation have been converted to hydroxyl groups.
