1-(2-Naphthyl)-2-(1-pyrrolidinyl)ethanone as a Photoinitiator for Methyl Methacrylate Polymerization

Abstract

2-Naphthyl)-2-(1-pyrrolidinyl)ethanone (MPY) was synthesized as a photoinitiator for free radical polymerization and the structure was characterized by spectral analysis. MPY has ability to initiate the polymerization of methyl methacrylate (MMA) monomer in air upon irradiation. Absorption and fluorescence properties of this initiator are investigated and the singlet excited-state energy value calculated in dichloromethane. According to the results, MPY acts as a type 2 photoinitiator.

Pyrazole-based photoinitiator with antibacterial activity

“…1). Molar absorptivity coefficient values of MPPY are similar to other synthesized acetonaphthone derivatives [23][24][25][26].…”

“…In the presented study, pyrazole based 1-(naphthalen-2-yl)-2-(1H-pyrazol-1-yl) ethanone (MPPY) was synthesized and characterized as a new photoinitiator in the light of α-amino acetonaphthone derivatives [23][24][25][26]. In addition, photochemical and antibacterial properties of MPPY were investigated for biomedical applications [27][28][29].…”

4-methyl-4-[2-(naphthalene)-2-oxoethyl] morpholin-4-ium iodide as a water soluble photoinitiator

“…Like other acetonaphthone type initiators, p→p* transitions are observed at wavelength about 305 nm and n→p* transitions are around 350 nm. It is also seen that the increase in solvent polarity has a hyperchromic effect (OD H2O >OD DMSO >OD DMF ) [16,17].…”

“…α-Aminoacetophenone and acetonaphthone derivatives are α-cleavable photoinitiators that have been synthesized in recent years. 2-(N-methyl-N-phenylamino)acetonaphthone (MPA), morpholino acetonaphthone (MPM) and pyrrolidine acetonaphthone (MPY) are synthesized by our group [14][15][16][17][18].…”
