a–d Three-dimensional models of assembly structures. e–h TEM images of TPE-DPY ([TPE-DPY] = 1 × 10−5 M), TPE-DPY/CB[8] ([TPE-DPY] = 1 × 10−5 M, [CB[8]] = 1 × 10−5 M), TPE-DPY/4CB[7] ([TPE-DPY] = 5 × 10−6 M, [CB[7]] = 2 × 10−5 M), TPE-DPY/CB[7]/CB[8]. ([TPE-DPY] = 1 × 10−5 M, [CB[7]] = 2 × 10−5 M, [CB[8]] = 1 × 10−5 M) (from left to right). i–l SEM images of TPE-DPY, TPE-DPY/CB[8], TPE-DPY/4CB[7] and TPE-DPY/CB[7]/CB[8]. Each experiment was repeated three times independently with similar results.
