Variable-temperature time-resolved emission spectra studies of random pyrene urethane methacrylate copolymers with high pyrene incorporation

A series of random co-polyurethane methacrylate comb polymers with pyrene (Py) and 3-pentadecylphenol (PDP) as pendant units were prepared by free radical polymerization. The pyrene labeling was varied from 1 to 100 mol %. The excimer emission of these copolymers were studied as a function of both time and temperature using time-resolved emission spectra (TRES) experiments and variable-temperature steady-state fluorescence measurements. Variable-temperature steady-state as well as decay experiments showed that the contribution from excimers via diffusional encounters increased at the cost of pyrene monomer as the temperature increased until a??50 C; beyond which nonradiative losses predominated. TRES collected at 25 and 70 C were compared to study the nature and origin of emitting species as a function of pyrene loading. TRES at 25 C clearly indicated the presence of ground-state pyrene dimers with emission centered at a??435 nm which soon gave way to emission centered around 465 and 485 nm in the time-gated spectra collected at higher time intervals. In TRES collected at 70 C, excimer emission centered at 465 and 485 nm was very high even at short time scales. The lowest pyrene loaded polymer PIHPDP-1Py did not exhibit excimer emission in the TRES collected at 25 C as well as 70 C. ? 2013 American Chemical Society.
HIGH ADHESIVE ACRYLATE MONOMER AND METHOD FOR PREPARING THE SAME

Page/Page column 4, (2009/07/17)
A high adhesive acrylate monomer has a specific chemistry figure. This monomer may be easily prepared in a simplified way, and various linkers may be used between L-DOPA and an acrylate group attached to a tail of L-DOPA, so molecular weight and size of the entire material may be easily controlled. Also, various kinds of acrylate to be combined to a isocyanate compound used as a linker may be selected, so various molecules may be easily composed.
