-
Paragraph 0042-0046, (2021/06/23)
The invention discloses a zinc-coordinated aza-pyrrolidone optical diagnosis and treatment reagent with a long-wave absorption characteristic as well as preparation and application thereof. The optical diagnosis and treatment reagent is composed of a metal center and an aza-pyrrolidone auxiliary ligand; the whole preparation process is simple, the prepared complex has a long absorption wavelength, and the absorption wavelength can be prolonged along with the change of the aza-pyrrolidone auxiliary ligand, so that the optical diagnosis and treatment reagent has a deep tissue penetration depth in the field of living body application; the complex can be excited by near-infrared light and can emit near-infrared light, so that the damage of an excitation light source to a biological sample can be weakened; and the complex can be used in the field of photodynamic and photothermal combined therapy guided by biological imaging, and has an important application prospect.

Paragraph 0040-0043, (2020/08/26)
The invention discloses an iridium coordination aza-pyrrolidone optical diagnosis and treatment reagent as well as a preparation method and application thereof. The complex is composed of a cyclo-metal ligand, a metal center and an aza-pyrrolidone auxiliary ligand, the overall preparation process is simple, and the prepared complex has a long absorption wavelength, so that the complex has a deep tissue penetration depth in the field of living body application and is more suitable for biological imaging. The complex has strong absorption in an ultraviolet region and a near-infrared region, andcan be excited by near-infrared light, so that the damage of an excitation light source to a biological sample can be weakened; and the complex can be used in the field of photodynamic photo-thermal combined therapy guided by biological imaging, and has important application prospects.

For the first time, a new solid acid catalyst has been used for the synthesis of aryl chalcones under solvent free conditions. A simple method (solid dispersion method) has been adopted for the synthesis of FeCl3/bentonite. The prepared catalyst has been characterized by different characterization techniques. A series of E-1-(substituted phenyl)-3-(1-pyrenyl)-2-propen-1-ones have been synthesized using FeCl3/bentonite under microwave-assisted solvent-free conditions. The yields are in the range from 80 to 88%. All the synthesized chalcones have been characterized by their physical constants, analytical, IR, 1H and 13C NMR spectral data. This catalyst can be reused for further runs (after fifth cycle) without decrease in activity. This catalyst gives excellent yields and is inexpensive and easily recyclable for this reaction.
