Photoinduced Fluorescence Patterning with a t-Boc Protected Dihydroxyphenylene Derivative

摘要

Generation of patterned functional images on solid substrates has attracted much attention owing to their potential technological applications. For instance, patterned fluorescent images could be utilized in many areas like displays, optical memory devices, molecular switches, sensors, and imaging industries. In general, fluorescence patterning on a solid substrate has so far been achieved by employing a so called 'two-step procedure', which involves the formation of reactive species such as amine, carboxylic acid, and hydroxyl groups in the first photochemical step. The reactive species in the exposed area then interact with fluorescent dyes (wet processing) in the second step.
