研究期間 (年度) 2019-04-01 – 2022-03-31
キーワードTerarylenes / X-Rays / Cascade reaction / Photophysics
研究実績の概要

This grant focuses on three key research areas (A, B and C).
C - Expansion of frameworks towards detection of X-rays: The initial detection of X-rays has been expanded and a and a recent paper published. A further five targets containing thieno-thiophene units to increase X-Ray absorption have now been prepared and fully characterized.
A - Optimization of the cascade reaction:
Investigations into variations in the electron donating abilities of molecular substituents has been carried out to optimize the the cascade reactions. This is ongoing with the first generation of eight molecules nearly complete and thermal and electrochemical analysis these ongoing.
B - Studies of the cascade reaction in plastic/solid media: This part of the project is aimed at year 3.

理由

This grant focuses on three research areas listed above (A, B and C).

C - Expansion of frameworks towards detection of X-rays: Five new targets have now been prepared and fully characterized. Their photophysical analysis is ongoing.
A - Optimization of the cascade reaction:
Preperation of the first generation of eight molecules is nearly complete and thermal and electrochemical analysis of these molecules is ongoing.

今後の研究の推進方策

This grant focuses on three research areas listed above (A, B and C).

C - Expansion of frameworks towards detection of X-rays: The analysis of these molecules is expected to be compete within the summero of FY2020. After this focus will shift to the other two parts of the project.
A - Optimization of the cascade reaction: Preperation of the first generation of eight molecules is expected to be complete by June 2020 (5 of 8 are already complete as of August 30) and differential scanning calorimetry and advanced electrochemical analysis of these molecules will begin in May/June 2020 and is expected to take 3-4 months. A second generation will be designed and synthesised during the lat half of FY2020
B - Studies of the cascade reaction in plastic/solid media: This is aimed at year 3.
