HC360 Plastic News: Recently, the research team led by Zhang Jian, a researcher in the State Key Laboratory of Structural Chemistry of the Fujian Institute of Physical Structure, Chinese Academy of Sciences, successfully synthesized optical MOF film materials loaded with ultra small carbon nano lattices.
The efficient and economical preparation of functional composite thin film materials is one of the challenges in the current research and development of new thin film materials, especially the preparation and application of optical functional composite thin films still need to be vigorously developed.

Carbon nanodots (CDs) have broad application prospects in catalysis, fluorescence, sensing, and biological imaging due to their high chemical stability, low toxicity, good biocompatibility, and excellent photophysical properties. The research team innovatively utilized the significant difference in carbonization temperature between MOF materials and glucose molecules to achieve the composite of carbon nanodots and MOF materials. The carbonization temperature of typical MOF materials should exceed 500 degrees Celsius, while the carbonization temperature of glucose molecules is around 200 degrees Celsius. Therefore, MOF materials loaded with glucose molecules maintain their skeletal structure unchanged at 200 degrees Celsius, but glucose is confined to the carbon nanodots in the MOF pores by carbonization behavior, resulting in uniformly dispersed MOF materials CDs@MOF compound material.
The size of carbon nanodots can be regulated by selecting MOFs with different pore structures. The prepared carbon nanodot supported MOF thin film not only has good morphology and optical transparency, but also exhibits tunable photoluminescence and photo limiting effects. This research work has achieved controllable synthesis of ultra small carbon nanodots in MOF templates and developed novel approaches CDs@MOF Composite optical limiting material, published in Angew. Chem. Int. Ed. 2017, DOI: 10.1002/anie. 201702162, German Journal of Applied Chemistry.
During the same period, the research team prepared porphyrin based PIZA-1 thin film materials (Small, 2017, 1160, 4035) that can efficiently and selectively detect volatile organic compounds. They explored the effects of growth orientation, thickness, and modified substrates of MOF thin films on the properties of MOF thin films and developed a series of thin film materials with chiral separation and catalytic functions (Chem. Commun., 2017, 531470; ACSApp. Mater. Interfaces, 2017, 97259; Inorg. Chem., 2017, 563526; Nanoscale 2017, DOI: 10.1039/C7NR02284K).
