5 FAQs about [Norbornadiene solar energy storage Monaco]
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.
Does naphthyl norbornadiene have favorable properties for chemical energy storage?
It was observed that these compounds have favorable properties for chemical energy storage. Specifically, 2- (1-naphthyl)norbornadiene showed a pronounced red shift of the absorption, a long half-life (35 d) and a relatively high energy storage density (361 KJ/Kg) of the respective quadricyclane.
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.
What is the absorption onset of unsubstituted norbornadiene 1?
The absorption onset of unsubstituted norbornadiene 1 is 267 nm, but since the intensity of solar radiation below around 300 nm is very low at sea level, norbornadiene is essentially inert to sunlight. To prepare quadricyclane, high-power ultraviolet lamps are employed, typically in the presence of a photosensitizer.
