Abstract
Novel thermoresponsive sensor systems consisting of a molecular rotor (MR) and paraffin wax (PW) were developed for various thermometric and biometric identification applications. Polydiphenylacetylenes (PDPAs) coupled with long alkyl chains were used as MRs, and PWs of hydrocarbons having 16-20 carbons were utilized as phase-change materials. The PDPAs were successfully dissolved in the molten PWs and did not act as an impurity that prevents phase transition of the PWs. These PDPA-in-PW hybrids had almost the same enthalpies and phase-transition temperatures as the corresponding pure PWs. The hybrids exhibited highly reversible fluorescence (FL) changes at the critical temperatures during phase transition of the PWs. These hybrids were impregnated into common filter paper in the molten state by absorption or were encapsulated into urea resin to enhance their mechanical integrity and cyclic stability during repeated use. The wax papers could be utilized in highly advanced applications including FL image writing/erasing, an array-type thermo-indicator, and fingerprint/palmprint identification. The present findings should facilitate the development of novel fluorescent sensor systems for biometric identification and are potentially applicable for biological and biomedical thermometry.

Abstract
Various bicolored fluorescent micropatterns are fabricated on a single polymer film by concurrent photobleaching and a photobase generation process. A polymer, bearing anthracene and oxime-urethane groups, is dyed with rhodamine B isothiocyanate after irradiation with 310-nm UV light. The photochemical reaction of the polymer is monitored by UV, IR absorption, and fluorescence emission spectroscopy. Differently colored fluorescent micropatterns are obtained by selectively exciting each dye moiety. Various bicolored fluorescent micropatterns are observed through varying the excitation wavelength and observation wavelength ranges using a confocal microscope. This bicolored fluorescence patterning method will be useful to apply in photonic/electronic devices.

Abstract
Micro- and nano-patterned fluorescent materials are important for many photonic devices and applications. In this paper, we investigate the impact of three common lithographical techniques, deposition and removal of sacrificial masks, ultraviolet ablation, and focused ion beam milling, on self-assembled fluorophores. We find that different patterning techniques can dramatically change the fluorescence lifetime of the fluorophores and that the degree of modification depends on the patterning techniques.
