The application of fluorescence techniques has been demonstrated for the study of four polymer problems: (a) If two different polymers are labeled with donor and acceptor fluorophores, respectively, which exhibit nonradiative energy transfer, the emi

Three types of investigations are described, (a) When a polymer chain carries reactive substituents, the reaction rate may be increased by very large factors if these groups are sufficiently close to each other. More distant groups interact at rates

The fluoresence intensity of dansyl residues attached to poly(acrylic acid) (PAA) increases sharply when PAA forms complexes with polyoxyethylene (POE) or poly(vinyl pyrrolidone) (PVP), because the emission from this chromophore is more intense in or

Green light-emitting GaP:N diodes (LED's) are investigated at room temperature using a scanning electron probe microanalyzer. Integral cathodoluminescence (CL) line scans across the p-n junction are carried out. The CL line scan is discussed in conne

Studies of fluorescence anisotropy, excimer emission, nonradiative energy transfer and the dependence of emission intensity on the polarity and rigidity of the medium have been applied to fluorophore-labeled polymers to characterize various aspects o
