Preparation of inverse opal cerium dioxide for optical properties research
Inverse opal cerium dioxide (CeO2) is prepared with polystyrene (PS) microsphere opal template and sol–gel method, and characterized in detail. The opal template and inverse opal CeO2 show different colors in the light of halogen tungsten lamp and have a long-range ordered three dimensional periodic structure. Comparing with the opal template, the size of the inverse opal CeO2 shows shrinkage. Th...

18. Hyperbranched fluorinated polyimides with tunable refractive indices for optical waveguide applications
A series of halogenated hyperbranched polyimides (HBPIs) with tunable refractive indices (RIs) has been designed and prepared for use as novel optical waveguide materials. The hyperbranched structure of these polymers leads to Multifarious and controllable chemical Structures. The degree of branching in these HBPIs was estimated using (1)H NMR spectroscopy. The halogen-terminated HBPIs were found ...

8. Synthesis of Novel Fluorinated Hyperbranched Polyimides with Excellent Optical Properties
Novel anhydride-terminated fluorinated hyperbranched polyimides (FHBPIs) were successfully prepared by condensation of a triamine monomer, 1,3,5-tris(2-trifluoromethyl-4-aminopheoxy) benzene (TFAPOB), and various aromatic dianhydride monomers with different linear length. UV-vis spectra indicate high optical transparency of FHBPI films with a UV-vis absorption edge of 350-395 nm. FHBPIs show incre...

Theoretical Study of Structures and Optical Absorption of Si172 Quantum Dots
The structures and optical properties of silicon quantum dots (QDs) have long been studied. Exploring the growth pattern of silicon crystal is challenging due to the competitions among various structural motifs. Here, about 1.7 ~ 1.9 nm silicon QDs (Si172 QDs) have been unbiased searched by genetic algorithm (GA) combined with a tight-binding molecul...

70. Facile one-pot synthesis of fluorescent hyperbranched polymers for optical detection of glucose
Fluorescent and glucose-sensitive hyperbranched poly(amidoamine)s (HPAMAMs-B) were synthesized via Michael addition of 1-(2-aminoethyl) piperazine (AEPZ), methyl acrylate (MA), and 3-aminobenzeneboronic acid (APBA). These hyperbranched polymers emitted chartreuse photoluminescence and showed emission band at 378 nm under excitation wavelength. The intensity of emission band was enhanced with incre...
