The existence of the reactive intermediate trans-10b,10c-dimethyl-10b,10c-dihydropyr-1-yne, 57, generated via dehydrobromination, was proved by trapping with N,N-diethyl-1,3-butadienylamine, furan and a series of isoannelated furans. Comparison of 57 with benzyne, 1, was implemented using the results of MMX/PCMODEL calculations. A fast route to annelated dihydropyrenes was developed via the reactive intermediate 57. Through this route, five annelated dihydropyrenes, namely, trans-14b,14c-dimethyl-14b,14c-dihydronaphtho (2,1,8-gra) naphthacene, 204, trans-16b,16c-dimethyl-16b,16c-dihydrobenzo (a) naphtho (2,1,8-fgh) naphthacene, 206a, trans-16b,16c-dimethyl-16b,16c-dihydrobenzo (a) naphtho (2,1,8-hij) naphthacene, 206b, trans-14b,14c,18b,18c-tetramethyl-14b,14c,18b, 18c-tetrahydrodinaphtho (2,1,8-uva; 2,1,8-jkl) pentacene, 224a, and trans-15b,15c,18b,18c-tetramethyl-15b,15c,18b, 18c-tetrahydrodinaphtho (2,1,8-uva; 2,1,8-pon) pentacene, 224b, and one bridged oxa (17) annulene, namely, trans-11b,11c-dimethyl-11b,11c-dihydropyreno (1,2-c) furan, 222, were synthesized. Metal complexation of the benzo (a) dihydropyrene 95 was investigated. This led to the first two metal dihydropyrene complexes, namely, (7,8,9,10,10a,10b-η6)-trans-12b,12c-dimethyl-12b,12c-dihydrobenzo (a) pyrenechromium(0)-tricarbonyl, 239, and (1,2,3,3a-η4) -trans-12b,12c-dimethyl-12b,12c-dihydrobenzo (a) pyreneiron(0)tricarbonyl, 209. The delocalization effects due to complexation were studied. Combining the results of the newly synthesized annelated dihydropyrenes with previously obtained ones, a series of correlations between theoretical calculations and experimental results, such as bond order vs. chemical shift, bond order vs. coupling constant, and ring current vs. chemical shift were devised. The ortho-metalation of dihydropyrene derivatives and synthesis of 1-bromo-2-fluoro-dihydropyrene were attempted. This led to two new dihydropyrene derivatives, namely, trimethylacetamino-trans-10b,10c-dimethyl-10b,10c-dihydropyrene, 99, and 2-diethylcarbamyl-trans-10b,10c-dimethyl-10b,10c-dihydropyrene, 109, and two new cyclophane derivatives, namely, syn-5-bromo-6-fluoro-9,18-dimethyl-2,11-dithia (3.3) metacyclophane, 131a, and anti-5-bromo-6-fluoro-9,18-dimethyl-2,11-dithia (3.3) metacyclophane, 131b. / Graduate

In this thesis, we develop the methodology for exploring the electronic and optical properties of an artificial benzene ring, both analytically as well as numerically through direct diagonalization using the configuration interaction method. We use the extended Hubbard Hamiltonian to model the interactions with different numbers of electrons, with spin projection and total spin resolved as good quantum numbers. The focus in this work is on the charged case and the emergence of an artificial gauge field and how it can be detected optically. We also examine three other cases of the artificial benzene ring, the single electron case, the charge neutral or half filled case, and the quarter filled case. Ground state properties, excited state spectra, and interactions with light are described.
