Molecular solar thermal (MOST) systems that undergo photoisomerizations to long-lived, high-energy forms present one approach of addressing the challenge of solar energy storage. For this approach to mature, photochromic molecules which can absorb at the right wavelengths and which can store a sufficient amount of energy in a controlled time period have to be developed. Here we show in a combined experimental and theoretical study that incorporation of a pyridyl substituent onto the dihydroazulene/vinylheptafulvene photo-/thermoswitch results in molecules whose optical properties, energy-releasing back-reactions and energy densities can be controlled by protonation/deprotonation. The work thus presents a proof-of-concept for using acid/base to control the properties of MOST systems.

5,6-Epoxy-5,6-dihydroisoquinoline 9 and 7,8-epoxy-7,8-dihydroisoquinoline 21 were each obtained by multi-step synthetic sequences from 5,6,7,8-tetrahydroisoquinoline 1.The mammalian metabolite, trans-5,6-dihydroisoquinoline-5,6-diol 10 was chemically synthesised by base-catalysed hydration of the isoquinoline arene oxide 9.
Applications of Organolithium and Related Reagents in Synthesis. Part 3. A General Study of the Reaction of Lithium Alkyls with Pyridine Ketones

, p. 213 - 220 (2007/10/02)
The reaction of MeLi and PhLi with acetylpyridines (1a-c) and their annelated derivatives (2a), (2b), (3), and (4) has been examined.The 3- and 4-pyridyl ketones (1b), (1c), (3), and (4) gave similar results to acetophenone and 3,4-dihydronaphthalen-1(2H)-one.In the case of the 2-pyridyl ketones (1a), (2a), and (2b) unexpectedly low yields of products resulted from the addition of RLi to the carbonyl group; the reaction was efficiently enhanced by initially adding an additional amount of LiBr.These results were accounted for by the chelation of RLi or LiBr by the 2-pyridyl ketones.
