“…22 This perspective motivates many of the recent studies of the optical absorption and luminescence properties of the collective exciton states in these systems, as well as the energy transport and relaxation caused by these states. [2][3][4][5][6][7][23][24][25][26][27] In homogeneous cylindrical aggregates, the rotational symmetry around the axis imposes strong optical selection rules on the wave number k 2 that characterizes the exciton's Bloch wave function along a ring around the cylinder. In particular, it is easily shown that only states with k 2 = 0 and k 2 = ±1 may carry optical oscillator strength.…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14] Examples of molecules that in solution self-assemble into aggregates of a tubular shape are carbocyanine molecules with hydrophobic and hydrophilic side groups [2][3][4][5][6][7] and porphyrin derivatives. [8][9][10][11][12] Both these molecules yield aggregates with a diameter of the order of 10 nm and a length of up to microns, which explains why they are often referred to as molecular nanotubes.…”

“…In a water−methanol mixture, C8S3 monomers self-assemble into nanotubes with an outer wall diameter of ∼12.5 nm, an inner wall diameter of ∼6 nm, and longitudinal dimensions tens of micrometers in length (panels b and d of Figure 1). 13,16 To accomplish our study, we have developed a method to stabilize C8S3 LHNs against light-induced and cryogenic damage in a sugar-based matrix. 19 We modify the normal preparation by diluting the aggregate preparation in a highly concentrated sucrose−trehalose solution and drying overnight to create a concentrated, clear, dry, sugar-glass matrix ( Figure 1c).…”

“…J-aggregate nanotubes are attractive for efficient electron transfers because they share the molecular packing feature with photosynthetic light-harvesting antennas [19]- [24]. In this paper, we report the formation of templated J-aggregate nanotubes by the adsorption of 3,3'-diethylthiacarbocyanine iodide (DTCC) on the self-assembled nanotubes of lithocholic acid (LCA).…”
