Table 1. Experimental Details of Five Selected NRs Used to Test the Methoda.
particle | micelle | seed diameter [nm] | seed height [nm] | diameter [nm] | height [nm] | expected handedness |
---|---|---|---|---|---|---|
R1 | (R)-BINAMINE | 46 | 139 | 127 | 216 | right-handed |
R2 | (R)-BINAMINE | 48 | 143 | 131 | 223 | right-handed |
S1 | (S)-BINAMINE | 46 | 131 | 135 | 212 | left-handed |
S2 | (S)-BINAMINE | 42 | 132 | 124 | 208 | left-handed |
R3 | (R)-BINAMINE | 43 | 131 | 81 | 177 | right-handed |
All NRs comprise a central achiral Au NR, on which a chiral Au shell was grown using surfactant micelle templating, using either (R)-BINAMINE/CTAC or (S)-BINAMINE/CTAC mixtures.
