Novel peptidomimetics containing dithiocarbamate groups were synthesized via the Ugi reaction. Also, dithiocarbamates of natural amino acids were prepared and were used successfully in Ugi reactions to prepare novel peptidomimetics bearing amino acid and dithiocarbamate groups in a single structure. In addition the prepared dithiocarbamates based on amino acids are converted to the corresponding amides
Dual-functional polydimethylsiloxane (PDMS) surfaces with antibacterial and antifouling properties were conveniently developed via a novel Y-shaped photoiniferter (Y-iniferter).
An electrophotographic photoreceptor improved in electrostatic characteristics and image pickup and particularly excellent in the reproduction of highly precise images by the use of a liquid developer and in the image pickup according to the scanning exposure system using low-output laser beams. The photoreceptor contains a binder resin comprising at least one resin (A) containing at least 30 wt% of a polymer component of general formula (I) and 0.5 to 15 wt% of a specified polar polymer component and having a weight average molecular weight of 1x10³ to 2x10⁴ and at least one resin (B) comprising an A-B block copolymer composed of block A containing a specified polar polymer component and block B containing a polymer component of general formula (I) and having a weight-average molecular weight of 3x10⁴ to 1x10⁶. In formula (I) a¹ and a² represent each hydrogen, halogen, cyano, hydrocarbyl, or COOR⁴ optionally bonded via hydrocarbyl (wherein R⁴ represents hydrocarbyl); and R³ represents hydrocarbyl.

Aspherical-polymer fine particles are resin particles synthesized by polymerizing radically radical polymerizable monomers in a non-aqueous solvent in the presence of a resin for dispersal stability, wherein the aspherical-polymer fine particles have a sphericity of 0.95 or less.
The invention provides a fluorescent polymer fine particle having at least; a polymer particle having a core-shell configuration having a hydrophobic core and a hydrophilic shell; and a fluorescent lanthanoid dye that is integrated with the polymer particle and has a fluorescent lanthanoid cation, wherein a hydrophilic polymer which forms the hydrophilic shell has a polymerizable unit and at least one hydrophilic unit selected from the group consisting of a hydrophilic (meth)acrylamide unit and a hydrophilic vinyl amine unit. The invention further provides a method for forming the fluorescent polymer fine particle having at least dispersing and polymerizing a hydrophobic radical polymerizable monomer in an aqueous solvent in the presence of a radical generator and the presence of a components for forming a hydrophilic polymer which forms the hydrophilic shell; and introducing the fluorescent lanthanoid dye with the polymer particle.
