| 논문초록 | Most organic luminescent materials have a fluorescence property and even if the phosphorescence occur, electrons at triplet states are consumed as a heat by vibration in a shorter time. The complex of ‘2,5-Dihexyloxy-4-bromobenzaldehyde(Br6A)’, ‘2,5-Dihexyloxy-1,4-dibromohenzene(Br6)’and ‘Poly(acrylic acid)(PAA)’ can emit phosphorescence with combination of two factors : Preventing self-quenching and enhancement of emission intensity by Cocrystal formation of Br6 and Br6A, Reduction of vibration loss by halogen bonding between PAA and Cocrystal. Phenol interferes with these two factors in the Cocrystal-PAA complex. As a result, we fabricated a visually identifiable phenol sensor by reducing the emission intensity of the complex by exposure to phenol. Nanofilaments are made from electrospinning to enhance detection rate of phenol using Cocrystal-PAA complex. These nanofilaments are have a higher surface area than made by other methods like drop casting, spin coating. |
