発明の名称 (英語) PORPHYRIN GLASS EMITTING NEAR INFRARED LIGHT 新技術説明会
発明の概要(英語) Provided is a near infrared light emitting material containing a porphyrin compound that is amorphous and is represented by general formula (I).
従来技術、競合技術の概要(英語) BACKGROUND ART
700-1400nm wavelength near infrared wavelength range of absorption of the biological tissue, scattering is minimal and referred to as a "window of a living body", in the medical diagnosis and treatment technique is particularly effective to the end of the wavelength region thereof. However, absorption, long wavelength emission HOMO-LUMO gap is so narrow, non-radiation deactivation rate increases and it is known (the energy gap law), in the near infrared wavelength range for emitting near infrared light-emitting material is a challenging issue of the development.
Moreover, HOMO-LUMO gap of the compound in order to reduce the expansion of the π conjugate π stacking associated with the non-light-emitting species and is easily, the development of near-infrared light-emitting material becomes important to control the state of association.
Non-Patent Document 1 is stacked on the π conjugated system to be individually composed of a repeated sequence of porphyrin pyridyl which discloses a porphyrin array of the duplex is, the near-infrared light-emitting material to be applied is not described.
