6 FAQs about [Bahamas norbornadiene solar energy storage]
Is norbornadiene a molecular energy storage system?
Due to its properties, the molecule pair norbornadiene (NBD) and quadricyclane (QC) appears auspicious concerning its feasibility as MOST energy storage system (see Section 1.2). MOST systems can also be considered as molecular photoswitches; 9 in this context, various systems are known in literature (see Scheme 1).
Does norbornadiene affect solar absorption?
Functionalization of the norbornadiene with donor and acceptor units has been used to tune absorption maxima, but this positive effect on solar absorption is counter-balanced by higher molecular weights, and hence lower energy densities 11, 16.
Are molecular solar thermal systems suitable for storing solar energy?
Molecular solar thermal systems are promising for storing solar energy but achieving high energy storage densities and absorption characteristics matching the solar spectrum is challenging.
Which Norbornadiene is best suited for solar spectrum match?
The most red-shifted absorption was observed for 4 d, with a maximum at 398 nm and an onset at 456 nm. Thus, among the synthesized compounds, 4 d is the norbornadiene that best meets the requirements of solar spectrum match.
Are norbornadienes a good candidate for a photoisomer?
Norbornadienes have shown to be a promising candidate for MOST due to the high energy difference between the norbornadiene (NBD) and quadricyclane (QC) photoisomer of approximately 96 kJ mol −1 (Fig. 1), and the system has been shown to undergo heat-release by the action of cobalt-based catalysts 11, 12, 13.
Can a strained valence isomer convert norbornadiene into a quadricyclane?
The photoinduced conversion of norbornadiene into its strained valence isomer quadricyclane is particularly promising. Challenges concerning the overall efficiency lead to the search for suitable molecule and catalyst design. This review covers important reaction steps during the heterogeneously catalyzed energy release in model surface studies.
