3 FAQs about [Norbornadiene solar energy storage Singapore]

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).

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.
