how show #comments link in a new page

Hi

I want showing comments of a post in a new page without showing contents.

for example : below a post show a link like :

domain.com/postname/#comments

that after clicking a new page appear that show comments.

I can do this by lightbox but that’s not good for comments that are several pages .

or

I need an if for single page that if the link of post is :
domain.com/postname
show content but not showing comments means omit :
<?php comments_template(”,true);?>
but if load :
domain.com/postname/#comments
omit content and showing :
<?php comments_template(”,true);?>
