Sunlight Energy Storing Chemicals
Photodimerization is the light induced formation of dimers. As early as 1909, the dimerization of anthracene into dianthracene was investigated as a means of storing solar energy. The photodimerization of the naphthalene series has also been investigated.
Photoisomerization is the light induced formation of isomers. Various ketones, azepines and norbornadienes among other compounds have been investigated as potential energy storing isomers. The norbornadiene-quadricyclane couple is of most potential interest for solar energy storage processes. The controlled release of the strain energy stored in quadricyclane (about 110 k J/mole) back to norbornadiene is made possible. Also, many different derivatives of norbornadiene has been investigated for this reaction.

Famous quotes containing the words sunlight, energy and/or storing:
“Weave, weave the sunlight in your hair—”
—T.S. (Thomas Stearns)
“After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
“Computers are good at swift, accurate computation and at storing great masses of information. The brain, on the other hand, is not as efficient a number cruncher and its memory is often highly fallible; a basic inexactness is built into its design. The brain’s strong point is its flexibility. It is unsurpassed at making shrewd guesses and at grasping the total meaning of information presented to it.”
—Jeremy Campbell (b. 1931)
