Abstract

The present disclosure is directed to designing dyes and methods to alter the parameters controlling the dipole-dipole coupling of dyes bound to a nucleotide oligomer architecture, which are used to propagate excitons for use in next generation room temperature quantum information systems. The disclosed dyes and methods are directed to changing the dye stability, symmetry, overlap, and steric hindrance of the dyes to fine tune aggregate systems.

First claim

What is claimed:

1. A method of engineering parameter J, said parameter J being an excitonic hopping parameter or a measure of a coupling strength, of two or more dyes within one or more dye aggregates or between two or more dye aggregates, comprising:
tuning the distance and/or an orientation between dyes and/or dye-to-dye intermolecular interactions; and
using a nucleic acid architecture to in part control the tuning.

2. The method of claim 1 , wherein the tuning of the dye-to-dye intermolecular interactions adjust one or more of hydrophobicity of the dye, symmetry, electronic factors, and/or sterics between one or more dyes.

3. The method of claim 2 , wherein the intermolecular interactions adjusted is the hydrophobicity of the dye.

4. The method of claim 3 , wherein the hydrophobicity is increased.

5. The method of claim 4 , wherein a number of alkyl and/or Cl substitutes on the dye is increased.

6. The method of claim 3 , wherein the hydrophobicity is decreased.

7. The method of claim 6 , wherein a number of SO 3 − substitutes on the dye is increased.

8. The method of claim 2 , wherein a steric hindrance between one or more dyes is tuned.

9. A method of engineering parameter J, said parameter J being an excitonic hopping parameter or a measure of a coupling strength, of two or more dyes within one or more dye aggregates or between two or more dye aggregates, comprising:
tuning the distance and/or orientation between dyes and/or dye-to-dye intermolecular interactions; and
using a nucleic acid architecture to in part control the tuning;
wherein a rotaxane ring and/or macrocycle is incorporated around or encapsulating one or more dyes.

10. A method of engineering parameter J, said parameter J being an excitonic hopping parameter or a measure of a coupling strength, of two or more dyes within one or more dye aggregates or between two or more dye aggregates, comprising:
tuning the distance and/or orientation between dyes and/or dye-to-dye intermolecular interactions; and
using a nucleic acid architecture to in part control the tuning;
wherein a rotaxane ring and/or macrocycle is incorporated around or encapsulating one or more dyes;
wherein the rotaxane ring and/or macrocycle is further substituted.

11. The method of claim 1 , further comprising tethering one or more dye aggregates to a nucleic acid architecture.

12. The method of claim 11 , wherein one or more dyes in the one or more dye aggregates is tethered by more than one tether and/or tethers of different lengths.

13. The method of claim 8 , wherein a number and length of alkyl substituents incorporated on the dye is increased.
